74ecff13ad GCC: Fixed __SIMD32 type punning warnings.
With help from https://github.com/ARM-software/CMSIS_5/issues/98

Using void* makes me really queasy though!

a1b9f4aa1b Simplify, generalize, share int16_t taps copy function.
Also prevents compiler loop unrolling in non-critical code, for code size improvement.

424c0eac3f FIRAndDecimateBy2Complex: expose decimation_factor, bring work function into class. 2015-11-06 09:40:04 -08:00

cde15e4271 Generalize fir_and_decimate_by_2_complex_fast.
Permit decimation_factors other than 2.
Permit tap counts != 64 (but still must be multiple of 8).
Half the amount of tap memory required.
Performance is significantly degraded due to greater flexibility -- most likely due to separate sample buffer shift phase, instead of performing shift during output sample calculation.
